WINDOW CONSTRUCTION.

Application filed May 1,

This invention relates to window constructions, and has for one of its ob ects the provision of a sliding sash adapted to be pivotally adjusted to an inwardly inclined ventilating position, and further adapted to be completely removed from its frame to facilitate washing the glass of said sash, or for other purposes.

Another object is to provide a sash mounting of the described character that may be applied to a sash already installed.

A further object is to provide a combined slide guide member and pivot mounting for a window sash that will also function as a weather strip.

The above and other objects will be apparent from the following description wherein reference is made to the accom panying drawings, illustrating a preferred embodiment of my invent-ion.

In the drawings,

Figure 1. is a perspective view of the improved window construction.

Figure v2 is a view of the same in inside elevation.

Figure 8 .is a cross-section view of the same on line 8--3 of Fig. 2.

Figure 1 is a perspective view of one of two sheet metal slides employed by the invention to carry a sash.

Figure 5 is a fragmentary view showing one position of the pivotal connection between the sash and a slide for the same.

In these vie s, the reference character 1 desi 'nates sash, fitted with glass 2, and mounted in a frame, the uprights or jainbs of which are designated at 3. The opposing faces of said uprights are provided with the usual vertically extended stop strips 4% between which slide-ways 5 are formed.

In the slide-ways 5, the invention mounts a pair of tubular rectangular sheet metal slide members 6, jointly supporting the sash 1. Said slides each have a wall 6 which bears against the sash 1, and which has a free edge 6 adjacent the outer wall of the slide. The latter, wall of each slide has free edge portion 6 projecting slightly beyond the wall 6* so as to form a. stop to hold the sash from outward swinging. The lower end of the sash carries a pair of op positely projecting pins 7 which engage in short diagonal slots 8 formed in the lower and portions of the slides 6.

13 formed by slots in the walls 6*, downwardly and outwardly inclining from the inner margins of said wall. It will presently appear that the pins 12 thus act as latch members to normally hold the sash 1. from inward swinging about its pivots.

To the slides 6, cords 15 are secured, shown in Figurev 1, for carrying the usual weights (not shown) for counter-balancing the sash 1, the back faces of said slides be ing formed in their upper portions with vertical grooves 16, through which said cords extend to openings 17 in said faces, through which the cords are passed. In-

may be knotted or otherwise secured.

In the use of the described construction, when the sash 1 is in closed position or is in any ordinary raised position, said sash lies vertically between the slides 6, bearing against the projecting margins 6 which restrain said sash from any outward swinging about its pivots 7. Inward swinging of the sash, wnen in the aforesaid positions is prevented by the engagement of the pins 12?, in the pockets 13. That is to say, the weight of the sash and its glass 2 tends to normally locate the pins 152 in the lower ends of the pockets 13. The. links 11 lie vertically between the guides 6 and the sash when the latter is in any of the aforesaid positions, the pins 10 occupying the upper portions of the slots 9 under such conditions.

To establish the ventilating position of the sash, shown in Figure 1, the sash is slid up slightly with an abrupt movement causing it to move relatively to the slides 6, such relative movement being permitted by a shifting of the pins 7 into the upper ends of their slots 8, the slots 9 allowing, at the same time, a vertical shifting of the pins 10. The efiect of such relative movement is to lift the pins 12 clear of the'pockets 13,

whereupon the sash may be swung inwardly about the pivots 7 to its inclined ventilating position. Such swinging movement is lim ited by the links 11, the pins 10 upon said links engaging at the termination of such movement in the lower ends of the slots 9. In returning the sash to its vertical position the pins 10 slide upwardly in the slots 9, permitting the links 11 to also move toward vertical positions. Finally the sash is abruptly lifted, relative to the slides, to permit the pins 12 to be entered in the pockets l3.

lVhen it is desired to completely remove the sash from its frame, said sash is first shifted to its inclined ventilating position. The links 11 are then sprung toward each other so that the pins 10 leave the slots 9; this permits the sash to be swung down to a horizontal position, pivoting upon the pins '7, said pins occupying the upper portions of the slots 8, during this inging movement so that the lower end of the sash may clear the edge portions (3 of the slides. The sash is now shifted bodily downward slight ly to engage said pins in the lower ends of the slots 8 (see Fig. and is swung; slight ly horizontally so that the slotted wall of one of the slides is sprung;- back from said sash, permitting the pin 7 which engages the other slide to leave its slot 8. That side of the sash which is thus freed from its slide is now tilted up, as shown in dash lines in Figure 2, whereupon the other pin 7 may be freed from its slide, and the sash lifted clear of the frame. I

It will be evident that by reversing the order of the described operations, the sash may be again returned to an operative engagement with its frame.

It will be noted that in the ventilating position of said sash, the glass thereof deflects incoming; air upwardly so thatthe occupants of a room will not be in the path of a direct draft.

The provision for complete removal of the sash, as described, permits cleaning of both sides of the ,QlRFS (orany other operation upon the sash or glass to be conveniently performed.

The members 6 function as weather strips as well as slides, since the walls 6 of said members press resiliently against the edges of the sash when the latter is in its closure forming position between said members.

The opposite edges of the sash l are preferably depressed somewhat throughout the area to which the arms 11 are adjacent, the accommodation of the arms in these depress ons 1S permitting; the walls 6 to bear throughout the major portion of their areanpon said edges of the sash.

From the foregoing description it becomes evident that the device is very simple and etiicient in operation, will not easily get out of order and provides a device which accomplishes the objects described.

lVhile it will be apparent that the illustrated embodiment of my invention herein disclosed is well calculated to adequately fulfill the objects and advantages prin'iarily stated, it is to be understood that the invention is susceptible to variation, modification and change within the spirit and scope of the subjoined claims.

Having thus described my invention, I claim:

1. In a window construction, the combination with a sash, and a frame for said sash, comprising; uprights between which the sash is engagcable, of a pair of slides arranged for vertical travel upon said uprights, pivot members carried by the lower end portion of said sash, engaging said slides, and adapted for a limited up and down movement in d slides, and pins oppositely projectin; from the sash at points remote from said pivot. members, the slides having pockets in which said pins are downwardly engagcable to normally hold the sash from swinging.

2. In a window construction, the combination with a sash, and a frame for said sash comprising uprights, between which the sash is engageable, of a pair of slides arranged for vertical travel upon said uprights, a pair of pivot members mounting the sash upon the lower end portions of said slides, and a pair of pins normally engaging the sash and slides under wcia'ht of the former to maintain the sash vertical and restrain it from swii'i zing on said pivot members, the sash being bodily vertically movable relative to said slides to re ease the connection established by said pins, preliminary to swinging said sash upon said pivot members.

3. Ina window construction, the combination with a sash. and a frame for said sash comprising uprights, between which the sash is engageable, of a pair of slides arranged for vertical travel upon said uprights, a pair of pivot members mounting the sash upon the lower end portions of said slides, connections between said slides and the sash for liinitin inward angular travel of the sash about said pivot members, said connections including pins, at opposite ends of the sash. the slides having pockets receiving said pins under weight of the sash. when the latter lies vertically between the slides, and the sash being adapted for a limited vertical movement relative to the slides to disentrace said pins from said pockets.

In witness whereof I hereunto set my hand.
